MASSAGE-MACHINE.

Specification of Letters Patent.

Patented Nov. 22, 1910.

Application filed April 13, 1909. Serial No. 489,694.

To all whom it may concern:

Be it known that I, EDWARD E. ZIEGLER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Massage-Machines, of which the following is a specification.

The present invention relates to massage machines; and particularly to the type in which an electric motor or some similar motive power is employed to drive the main shaft of the massage machine, the motor being in some cases connected directly to the main shaft and in others by the interposition of a flexible shaft as may be desired.

The object of the invention is the construction of a massage machine having few working parts and these of a strong and durable nature.

A further object is to reduce friction of the working parts to a minimum, particularly when pressure is applied to the brush and to provide a simple and inexpensive device for general domestic use.

The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this specification. For a better understanding of the invention, however, and the advantages possessed by it, reference may be had to the accompanying drawings and descriptive matter in which I have illustrated and described one of the forms in which my invention may be embodied.

Of the drawings, Figure 1 illustrates a side elevation of a massage machine embodying my invention. Fig. 2 is a longitudinal section of the same showing the internal construction of the device and the manner of operating the main shaft by a flexible shaft connection. Fig. 3 represents a vertical section taken through the body of the massage machine as indicated at 3-3 in Fig. 2. Fig. A is a detached side elevation of one of the working parts adapted to support the brush.

A is the cylindrical casing of the machine and is provided with an inclined stem A which is detachably secured to a handle A by a pin a B is the main driving shaft of the machine fitted to a reduced portion A of the casing and having a grooved head B to receive a row of balls I), 6, etc, which are serves as a bearing for interposed between the head and a similarly grooved collar C. The shaft B together with the head B is provided with an eccentric hole B to receive a secondary shaft D, one end of which is threaded at D to recelve a brush G. The shaft D which constitutes the brush holder is also provided with an enlargement D which rests in a corresponding opening in the head B and a row of balls arranged between the enlargement D and the head B of the shaft B. The enlargement D of the shaft D has a hole D to receive a rod E, which serves to prevent the shaft D from turning when the machine is in operation. The rod E is provided with a spherical head E which rests in a socket F of a collar F. In order to take up lost motion between the head E and socket F and thereby prevent undue vibration, the rod E is bored out and fitted with a pin E which under the influence of a spiral spring S is caused to bear against the casing A. To the threaded end D of the shaft D, is fitted a brush Gr, which may be of any desired shape, the form shown however consisting of a rubber disk provided with a number of pins, G G etc., and having a metal hub G internally threaded to the portion D of the shaft D.

The machine is preferably operated by means of a flexible shaft H, although if desired the motor or other source of power may be directly connected to the shaft B. I prefer, however, to operate the machine from the source of power by means of a flexible shaft H as shown in Figs. 1 and 2, one end of which is connected to the shaft by entering an opening B therein and being held in place by a set screw 6 Surrounding the flexible shaft H is a cover I, threaded to a sleeve J, which is secured to the casing A by a coupling K.

Having described my invention what I claim as new and desire to secure by Letters Patent is 1. A massage machine, comprising a casing, a main shaft, a secondary shaft journaled within the main shaft, a massage imlement attached to the secondary shaft a ulcrumed rod passing through the secondary and adapted to prevent the same from turning, and a spring pressed pin interposed between the rod and casing of the machine.

2. A massage machine, comprising a casing, a main shaft, a secondary shaft carried by the main shaft and adapted to move in a path eccentric to the main shaft, a massage implement attached to the secondary shaft a rod adapted to pass through an opening in the secondary shaft, a collar mounted within I l said head, a secondary shaft eccentrically mounted within the main shaft, a massage implement attached to the secondary shaft a row of balls interposed between the main shaft and secondary shaft, a rod fulcrumed to the casing and passing through an opening in the secondary shaft to prevent the secondary shaft from turning.

In testimony whereof I afiiX my signature in presence of two Witnesses.
